I'd do 4.10's if thats your main concern. If you're mostly wheeling it, then I would agree with 4.56.
Personally I was planning on 4.10's and 33's, but I've stepped up my plan to 4.56's and 35's. Mind that I commute in my Jeep, at least until I can afford a driver car

WheelinJR should SPOBI.
4.10's and 33's is a little on the doggy side of things. Low RPM's at highway speeds. Not good if you are looking for fuel economy. I wish I had the cash to go 4.88's. Currently have the 4.10's and 33's. 13MPG is as good as it gets for me, and that is with a corrected speedo.
If you are turning 33's and shooting for best MPG's, I'd say 4.56's would be the way to go.....possibably 4.88's. Definitely not 4.10's.

It revs a little high on the highway(about 2700rpm at 70) and if you would like to go over 80mph for long periods of time I would probably go with 4.10's but if you have the AW4(auto) I have heard that 4.56 with 33's make a sweet combo.

WheelinJR said:Whether or not its bogus is purely opinion and experience based. So here is my experience.
My current Jeep has 32's and 3.55's and if i drive in 3rd (maintain between 2200 and 2800rpm) with the AW4 I get about 14mpg
Driving in OD I maintain about 16-17mpg and that cruises on the freeway around 1500-1800
I get a couple more mpg maintaining the lower rpm on the freeway
M4Madness said:Everything I've read indicates that you get your best MPG out of the 4.0L engine when RPM's are somewhere between 2100 and 2500.
Pete M said:Another option is get a cheap econo car and watch your mpg double.
That answered your question. Get 4.56's.WheelinJR said:Thats my ultimate plan for someday. Some kind of Geo Metro or small Honda Civic from the late 80's/early 90's
